and seventy-third sessions of GRE. The modifications to the existing text of the
Regulation are marked in bold for new or strikethrough for deleted characters .

“Appendix 23
Measurement method for broadband electromagnetic emissions
created by the trolleybus”
1.
General provisions
1.1
The method described in this Appendix shall be applied only to trolleybuses
1.2
Test method
This test is intended to measure the broadband emissions generated
by electrical or electronic systems fitted to the trolleybus.
2.
Trolleybus state during tests
The trolleybuses shall be tested in the stationary state as well as at
the speed in steady and transit modes. The readings from the interference meter at the moment when the current collector passes by
points of rigid attachment of contact conductors are noted separately.
2.1
Operation mode of traction engines
2.1.1
Steady mode – the mode at which the voltage on traction engines of
the trolleybus isn't regulated: the traction mode - voltage on engines is given, the run-down mode - voltage is removed from engines.
5
2.1.2
Transit mode – the mode at which there is a voltage commutation of
traction engines: start, electrical braking, load shedding.
2.2
Others trolleybus systems
2.2.1
In the course of testing in the stationary state, static auxiliary converters (the maximum level of emissions isn't surely noted at the
maximum loadings) and systems of pulse regulation (at their exis tence) have to work, and the traction converter has to be energized,
but not operable.
2.2.2
All equipment which can be switched on permanently by the driver
or passenger should be in normal operation in maximum load, e.g.
wiper motors or fans. Horn and electric window motors are excluded because they are not used continuously.
2.3
In the course of testing in t5he driving mode the speed has to be rather low to avoid sparking in the sliding contact piece or its boun cings, and rather high to allow electric braking. The recommended
range of speed makes 35 ± 5 km/h. When passing a zone of antenna
measurement the vehicle has to be accelerated or decelerated using
about 1/3 from maximum traction force in this speed range.
3.
Measurement facility
3.1
Area for measurement interference caused by trolley, should be
smooth, free from buildings, trees, bushes, foreign air networks and
other objects within a radius of at least 25 m
3.2
The antenna shall be positioned between contact line supports in
the middle of the passage at a distance of 10 m from the track centre.
3.2.1
The vertical distance from the antenna to the ground:
- magnetic antenna - 1-2 m;
- electrical antenna - 2,5-3,5 m
II.
3.3
The measurements shall not be conducted in rainy or snowy weather as well as in case of clear ice and frost on contact system wires.
4.
Test requirements
4.1
The limits apply throughout the frequency range 0,009 to 0,150
MHz, 0,150 to 30 MHz, 30 to 1000 MHz for measurements performed in an outdoor test site.
4.2
Measurements can be performed with either quasi-peak or peak detectors. If peak detectors are used a correction factor of 20 dB as
defined in CISPR 12 shall be applied.
Justification
Proposals comprise the updated limits for broadband emissions and description of test methods for trolleybuses, which are based on IEC standards.
